Abstract: | The morphology evaluation of the sternal end of the fourth rib through the ??can’s “phases method” is considered one of the most reliable method for age-at-death estimation of corpses of unknown identity. This study aims to develop a component model for age estimation alternative to ??can’s method. A numerical score, ranging from 3 to 9, was assigned based on the morphology of surface (S), antero/posterior walls (W) and articular margins (M) of the sternal end of the fourth rib in 71 white female corpse. For each component a regression formula was determined. The best correlation between end rib morphology and age-at-death was obtained through the formula of multiple regression with two independent variables (articular surface and antero/posterior walls): Age (years) = 6.37(S) + 5.33(W) ? 17.15 ± 3.3. |
